Ghostbusters Proton Pack Bottom Plate with USB

This is a basic model of a bottom plate for a Ghostbusters proton pack. The plate follows dimensions from Stefan Otto's published blueprints–i.e., 39.3mm x 69.8mm x 12.7mm.

This plate is special because it includes a slot for a USB extension. The slot is sized for this particular extension with ABS shrinkage in mind:

The extension can be used for charging or programming internal electronics. The extension fits snugly into the slot but can be secured with screws.

The screw holes are sized to fit M3 press-fit threaded inserts from McMaster Carr:

I have included the Fusion 360 archive file and a .step file if you want to resize the slot for PLA or change the slot or screw holes.

Print instructions

Print the plate however you see fit. You can print it with 2-3 perimeters and 5-10% gyroid infill. Those settings will create a strong plate you can sand and finish.

If you intend to use heat inserts for the screws, print the plate 1-2 additional perimeters.
